The Kathmandu Kora Cycling Challenge is a yearly event started by Social Tours in 2011. Starting with just 35 riders who rode a 50km trail around Kathmandu and raised Rs. 0.45 million for charity, it has now grown to a massive 3000 rider event that has raised over Rs 5 million in its five years of running. In an effort to promote this event and to establish the standards that Great Himalaya Trails (GHT) adheres to, this year Samarth-NMDP supported the event with a promotional video and in making the cycling routes informative and standardized with signage boards along the trails.
